Page 3: Background/Introduction
Background/Introduction This guide discusses using the Tektronix TDS 2012 Digital Storage Oscilloscopes to make simple voltage versus time measurements and perform/use elementary functions. Figure 1 shows the front panel of the oscilloscope. Digital storage oscilloscopes sample analog signals, store the values (and corresponding times), and display them on the screen.

4/18 tds2012_oscilloscope_guide.doc Simple voltage measurement and display For the simplest case of a single self-triggering measurement, connect a P2200 passive probe to the CH1 BNC connector and the tip of the probe to the component/device whose voltage is to be measured.

Page 5: Channel Menus
5/18 tds2012_oscilloscope_guide.doc Channel menus The yellow CH1 MENU and blue CH2 MENU buttons are used to cause the oscilloscope to either display or hide the signal from the corresponding channel (yellow trace for CH1 and blue trace for CH2). In addition, when the particular channel is selected, a softkey menu for that channel will be activated.

Page 6: Set To Zero
6/18 tds2012_oscilloscope_guide.doc Set to zero Under the “HORIZONTAL” menu, the SET TO ZERO button sets the horizontal position (controlled by the horizontal position knob) to zero (center vertical axis), thus centering the signal horizontally. Help The oscilloscope has a Help system with topics that cover all the features of the oscilloscope. You can use the Help system to display several kinds of information: 1) general information about understanding and using the oscilloscope, 2) information about specific menus and controls, and 3) device about problems you may face while using an oscilloscope (e.g., reducing…

Page 8: Save/Recall
8/18 tds2012_oscilloscope_guide.doc The + and — options will display the sum or difference of the two signals on the display. It is important to note that the sum or difference will be calculated using the visual signals on the display. This means that if one signal is displayed to a higher magnification level (i.e., different VOLTS/DIV setting) than the other, the result will not be a true sum or difference.

Page 9: Measure
9/18 tds2012_oscilloscope_guide.doc You can choose an FFT window to eliminate discontinuities that will disrupt your output. As shown in Table 3, there are three window choices. Table 3 FFT window options Problems occur when the oscilloscope acquires a time-domain waveform containing frequency components that are greater than the Nyquist frequency.

Page 10: Menus
10/18 tds2012_oscilloscope_guide.doc There are several options for eliminating aliasing: 1. Adjust the Sec/Div control to a faster setting. This will raise the Nyquist frequency and bring the FFT display within range of the aliases. 2. If you do not need to view frequencies components above 20 MHz, set the Bandwidth Limit option to On.

TDS1000 and TDS2000 Series Oscilloscopes. Colorful
Performance at a Black and White Price.
The TDS1000 Series and TDS2000 Series digital storage
oscilloscopes deliver an unbeatable combination of superior
performance, unmatched ease-of-use and affordability in an
ultra lightweight, portable package. These new products
extend the performance and ease-of-use features in the
former TDS200 Series
the benchmark for low-cost oscilloscopes.
Affordable Digital Performance
With up to 200 MHz bandwidth and 2 GS/s maximum sample rate,
no other color digital storage Oscilloscope offers as much
bandwidth and sample rate for the price. The TDS1000 and
TDS2000 Series oscilloscopes provide accurate real-time acquisition up to their full bandwidth. These instruments offer advanced triggering, such
as pulse width trig gering and line-selectable video triggering, and 11 standard automatic measurements on all models. The Fast Fourier
Transform (FFT) math function allows the user to analyze,
characterize and troubleshoot circuits by viewing frequency
and signal strength (standard on all models).
Simple User Interface
The simple user Interface makes these instruments easy to
use, reducing learning time and increasing efficiency.
Classic, analog-style controls provide instant, front-panel
access to the most frequently used functions. The autoset
function automatically detects sine waves, square waves and
video signals, and provides readouts of relevant
measurements. This function also allows the user to select
additional views of the signal, such as rising and falling
edges, video lines and fields, and FFT. The Probe check
wizard aids the user in setting the attenuation factor and
compensating the Probe. The context-sensitive help menu with
indexed and hyper-linked topics allows the user to
selectively learn about the operation of any Oscilloscope
function. The color LCD display on the TDS2000 Series models
dedicates a different color for each trace and its
associated readouts to simplify viewing complex signals on
multiple channels.
